It recommends the computer system's flexibility control,the in-line adjustment of fixed length accuracy and reliable design of new type welded pipe fixed length flying saw.

The design of automatic trace flying saw machine based on DSP;

Several control programs for the flying saw machine have been analyzed and compared from the aspects of the machinery,electric apparatus,control principle,sizing accuracy of the welded pipe and the productivity effect,which set forth it is the optimized choice that the PLC control technology can replace the conventional control method.

In this system,the PLC and the DC speed-regulator are combined to simulate the operation of flying saw machine.

The drive system for φ325 flying saw of automatic numerical control;

The article points out that only milling flying saw by numeric control can solve the problems existed in traditional flying saw after the contrast and analysis of national existed flying saw.

This article has described the design and selection of the simultaneous mechanism,the saw cutting mechanism and the sizing mechanism for the cold rolling mill flying saw,further the selection of the saw blade structure parameter and process parameter have been emphasized as well.
